(3) reflection of light due to the presence of free electrons Explanation: Lustre (or luster) is the way light interacts with the surface of a crystal, rock, or mineral. The word traces its origins back to the latin lux, meaning "light", and generally implies radiance, gloss, or brilliance. Metals in general have high electrical conductivity, high thermal conductivity, and high density. Typically they are malleable and ductile, deforming -under stress without cleaving.

Description :  Every year before the Diwali festival, the kumaran stores increases the price of the product by 48% and then introduce two successive discount of 12% and 13% respectively. What is percentage loss and percentage gain ?

Last Answer : Let CP = 100,  48 % increase =>SP = 148 12 % discount in SP => ((148 x 12)/100) = 17.76 So 1st SP = (148 – 17.76) = 130.24  13 % discount in 1st SP ((130.24x13)/100) = 16.93 2nd SP = 130.24-16.93= 113.31 So finally CP = 100, SP = 113.31 => gain = 13.31%

Description : In a certain occupation, the profit is 110% of the cost. If the cost increases by 13% but the selling price remains constant, approximately what percentage of the selling price is the profit?

Last Answer :  Let Cp= RS.100 Profit= Rs 110 Sp= Rs 210 New Cp= 113%0f Rs.100=Rs. 113 New SP= Rs. 210 Profit= Rs. (210-113)= Rs. 97 Required %= 97/210*100=46%

In a certain office, the profit is 160% of the cost. If the cost increases by 12% but the selling price remains constant, approximately what is the percentage profit?

Description : In a certain office, the profit is 160% of the cost. If the cost increases by 12% but the selling price remains constant, approximately what is the percentage profit?

Last Answer : Let cost price = Rs.100 ; then profit = 160  Selling price = Rs.260 ; new cost price = 112% of Rs 100  New cost price = 122 ; new selling price = Rs 260  Profit = 260 – 112 = Rs.148  Required percentage = (148/112 *100)%  = 132.14%

In a certain mall, the profit is 160% of the cost. If the cost increases by 12.5% but the selling price remains constant, approximately what percentage of the selling price is the profit?

Description : In a certain mall, the profit is 160% of the cost. If the cost increases by 12.5% but the selling price remains constant, approximately what percentage of the selling price is the profit?

Last Answer : Let C.P.= Rs. 100.  Then, Profit = Rs. 160, S.P. = Rs. 260. New C.P. = 112.5% of Rs. 100 = Rs. 112.5 New S.P. = Rs. 260. Profit = Rs. (260– 112.5) = Rs. 147.5 Required percentage = 147.5/260*100=57% (approx.)

The population in a small town increases from 50000 to 63750 in one year. Find the percentage increase in population. a) 25 b) 62 c) 6.25 d) 27.5 e) 59.8

Description : The population in a small town increases from 50000 to 63750 in one year. Find the percentage increase in population. a) 25 b) 62 c) 6.25 d) 27.5 e) 59.8 

Last Answer : Answer: D Population in a small town last year = 50000 Population in a small town after one year = 63750 Increase in population = 63750 - 50000 = 13750 Therefore,  percentage increase in population = ... /50000 100  = 1375000/50000  = 27.5% Thus, the increase in population is 27.5%
